FASTENING.

Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed. February 19, 1910. Serial No. 544,744.

To all whom it may concern:

Be it known that I, ALVIN L. Canaan, a citizen of the United States ofAmerica, and resident of Des Moines, Polk county, Iowa, have invented anew and useful Fastening, of which the following is a specification.

The object of this invention is to provide improved means for connectingtwo objects.

it further object of this invention is to provide an improved detachablefastening to connect two flexible objects or a flexible object to arigid object, such as may be found in the construction of buggy tops,carriage tops, curtains and the like.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claimsand'illustrated by the accompanying drawing, in which Figure 1 is a faceView showing two of my improved fastenings employed to connect twoflexible devices to a thlrd device. Fig. 2 is an edge view of the deviceshown in Fig. 1. Fig. 3 is a face View of a back plate employed in mydevice. Fig. 4: is a face view of a face plate or housing, in extendedform, employed in my device. Fig. 5 is a face view of a latch plateemployed in my device. Figs. 6 and 7 are face and end views respectivelyof a modified form of my device.

In the construction of the device as shown in Figs. 1, 2, 3, 4; and 5the numeral 10 designates a back plate formed with slots 11 near andparallel with the side and end margins thereoff A face plate is formedwith notches 13, 14 in the corners of one end portion. Prongs 15 areformed on and extend laterally from the side margins and one end marginof the plate 12. The side marginal portions of the plate 12 are adaptedto be bent on parallel lines, indicated by dotted lines 16 in "F ig. 4,to produce flanges 17, 18, and one end marginal portion of said plate isadapted to be bent at right angles to the body of the plate, asindicated by dotted line 19 in Fig. 4, to form a flange 20 at rightangles to the first flanges. The face plate 12 also is formed with alongitudinal slot 21 and notches or transverse slots 22, 23 are formedin said plate and open to said slot. The notches or transverse slots 22,23 are arranged at acute angles to the slot 21. The plates 10 and 12 areof such size that when laid on opposite sides of an object, such l as acurtain 24, the prongs 15 on the plate 12 can be passed through theslots 11 of the plate 10 and in so doing penetrate and pass through theobject between the plates, and then be clenched against the rear face ofthe latter plate. The flanges 17, 1.8 and 20 and the body of the plate12, together form a housing. By means of the clenched prongs 15 thehousing, object 24 and back plate 10 are rigidly connected and theplates are firmly mounted on the curtain. A latch plate or eye-plate 25is provided and is adapted to be mounted for longitudinal slidingmovement between the housing plate 12 and the curtain 2 1. The latchplate 25 is formed with a key-hole slot 26 arranged longitudinallyadjacent one end thereof, the portion of said slot having the greatestwidth being toward the center of the plate. The latch plate 25 also isprovided with a slot 27 arranged obliquely in the end portion of saidplate opposite the slot 26. At times the latch plate 25 is adjustedbehind the housing plate 12 in such manner that the slot 27 registerswith one or another of the notches or transverse slots 22, A stud 28 ismounted with its stem extending through the notch 22 or 23 and throughthe slot 27 and the inner end of said stem is riveted loosely at therear of the latch plate, the head of said stud sliding-1y engaging thefront face of the housing plate. The stud 28 is loose relative to theplates 12 and 25 and yet on account of the loose riveting of the innerend of the stem it retains a connection with the latch plate. A stud,pin or similar object is mounted on a support 30 such as a prop, brace,seat-frame, top-strip or other device. When it is desired to fasten thecurtain 24 in extended position, the stud 28 is moved upwardly out ofthe notch 22 or 23 and along the slot 27 and then is movedlongitudinally of the slot 21, carrying with it the latch plate 25 intosuch position that the circular part of the slot 26 can be passed overthe head of the stud 29. This done, the stud 28 is moved rearwardly andmoves the latch plate 25 to its normal position causing the neck of theslot 26 to engage the neck of the stud 29. The stud 28 is moved farenough to stretch the curtain 24: and until said stud is opposite anotch 22 or 23 and then said stud is moved into said notch andeffectually locks the latch plate against outward longitudinal movement.The notch 22 is employed when the curtain is new and unstretched and thenotch 23 is employed when the curtain is old and stretched, thusproviding an adjustment for various uses under different conditions.Thus is the fastening device attached to the stud 29, and suchattachment is susceptible of release only through manipulation of thestud 28.

In Figs. 1 and 2 I have illustrated .the employment of two fasteningdevices in conjunction with a single stud 29, thus providing forattaching two curtains or similar objects to a single support orrelatively stationary object such as 29.

It sometimes occurs that it is desirable to attach the fastening deviceto a stud at right angles to the position shown in Figs. 1 and 2, and onthis account provision is made for bending the latch plate on a linecrossing the keyhole slot 26 as shown in Figs. 6 and 7. The latch plate25*, of modified form, is nianipulated to engaging or unlatchingposition identically is the other device, and

when in engaging position the neck of the be clenched behind the slotsof the base plate, a latch plate loosely mounted between the housing andbase plates, said latch plate formed with a keyhole slot and atransverse slot, the housing plate formed with an angu lar slot, thetransverse portion of which registers with the transverse slot of thelatch plate, and a stud mounted to travel in said slots and rivetedbehind the latch plate.

2. A fastening, comprising a back plate, a hosing plate provided with aslot and fixed to and connecting an object to said back plate, a latch,plate mounted between the housing and back plate, a stud slidably connected with the latch plate and extending outwardly through the slot inthe'housing plate, said latch plate formed with an engaging slot, anda'stud adapted to be engaged by the engaging slot of the latch plate.

3. In a fastening, a housing formed with an angular slot, a latch platemounted adjacent and slidable relative to said housing, and a studmounted in and slidable relative to said latch plate, said studextending through and slidable in said angular slot of the housing.
